The Washington Post reports a newly completed internal audit of security contracts at U.S. embassies abroad found that none of those examined had fully complied with vetting and other requirements for contractors who provide the first line of defense against attack. The audit, to be released Friday by the State Department’s Inspector General, was conducted in the wake of the 2012 attacks on the U.S. mission in Benghazi, Libya, that left four Americans dead. Local guards contracted to secure the perimeter and entry to the diplomatic compound there were found to have fled or failed to perform their duties. Of six embassies selected for review based on location and terrorism threat level, “none . . . fully performed all vetting requirements” for local guards, placing “embassies and personnel at risk,” the inspector general audit said. Chief diplomatic security officers at five of the six were said to have performed “inadequate oversight” of local guard vetting.
